Specification of Letters Patent.

Application filed March 6, 1912. Serial No. 681,906.

Patented Dec. 31, 1912.

To all whom it may concern:

Be it known that I, JOSEPH S. KING, a citizen of the United States ofAmerica, and resident of Baltimore city, in the State of Maryland, haveinvented certain new and useful Improvements in Measuring Devices, ofwhich the following is a specification.

This invention relates to measuring devices, particularly to meansdesigned primarily for use as attachments for bottles containinggranular material which is to be dispensed therefrom in predeterminedquantities as for instance head-ache remedies and other medicines andmaterials usually dispensed at drug stores and other places where apredetermined amount is allowed for each portion or drink served at asoda water fountain or the like.

An object of this invention is to provide novel means for measuring anddischarging successively the contents of a bottle or container, the saidinvention being designed to operate in such a way as to preventaccumulation or lodgment of material Within the measuring device, thesaid invention sewing to agitate the material to a sufficient.

extent as to cause it to be dislodged and to pass from the measuringreceptacle.

A still further object of this invention is to provide a measuringdevice which is manually operated to open and deliver the material,means being provided forauto-- matically closing the same for repetitionof the operation.

Wit-h the foregoing and otherobjects in view, the invention consists inthe details of construction and in the arrangement and combination ofparts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to theaccompanying drawings forming part of this specification wherein likecharacters denote corresponding parts in the several views, and inwhich- Figure 1 illustrates a front elevation of a measuring deviceembodying the invention;

. Fig. 2 illustrates 'a side elevation of the same; Fig. 3 illustrates asect-ion taken on the line 33 of Fig. 2; Fig. 4 illustrates a sectiontaken on line 4-4 of Fig. 1; Fig. 5 illustrates a detail View of aportion of the device slightly modified; and Fig. 6

illustrates a detail view of a link for connecting the crank handle witha lower trap.

In these drawings, 10 denotes a casing, or chute with which the traps 11and 12 are associated, the said trap 11 being in the form of a valvemounted on a shaft 13 and secured thereto by any suitable device such asa cross pin 14. The shaft 13 is journaled .in the casing and. terminatesin a crank handle 15 having its end weighted to hold it normallydepressed, the said trap 11 being so positioned, when the handle is inits depressed position that it stands vertically, or approximatelyvertically, in the casing to permit material to pass thereby into thecasing, the said material being held by the door or trap 12 whichnormally closes the lower end of the casing when the trap 11 standsvertically therein.

The trap 12 is mounted on a pivot 16 supported by the cars 17 preferablyformed integral with the casing, the said trap 12 hav ing a tail pieceor lug 18 to which a link 19 is pivoted, the said link extending to andbeing connected to the operating crank handle 15'by the pin 20 which iseccentric to the shaft so that as the crank handle is moved to partiallyrotate the shaft on which it is secured or of which it forms a part,motion is communicated to the trap 12 through the link and to the trap11 through the shaft. I

As will be observed, the parts are so organized that the traps arealternately in position to guard the opening through the casing so thatwhile the trap 12 is opened to discharge the material, the trap 11 liesacross the channel in the casing and prevents material from passingbeyond the trap 11.

The casing 10 has a nipple 21 which is I that the same may bepractically air-tight and liquid proof.

As shown in the modification, Fig. 5, in-

stead of having the crank handle provided with a weighted end, I mayprovide a spring A which bears against a portion of the mechanism forforcing the trap at the end of the casing-into closed position, andsince the other trap is operatively connected thereto, the said trapsare made to oppositely move into and out of position to guard theopening to the casing. The provision of the spring for holding the trapsclosed prev vents movement of the said traps which might otherwise occurin the event of the container being manipulated or moved from an uprightto an inverted position, or vice versa.

In Fig. 6 I have shown a detail view of the link 19, one end of which isshown as having a longitudinally disposed slot B which receives the pinin the crank arm and allows the pin to move a predetermined distancebefore communicating motion to the link. This relation of parts providesfor a lag or rest of the lower trap while the trapv to which the crankhandle is connected is being moved to close the passage through thecasing and it is a desirable feature, for the reason that it preventsdirect communication between the nipple portion of the casing and themeasuring portion thereof prior to the time the end of the casing isclosed by the trap 12, and this arrangement prevents the discharge ofmaterial from the container directly through the casing without itsbeing measured.

It will be understood that I do not wish to be limited with respect tothe exact details of construction or the particular use to which thisinvention is applicable, as it has been found in practice that I mayutilize it for measuring of comparatively minute quantities and that itis likewise useful for measuring comparatively large quantities ofgroceries, merchandise and the like; furthermore I wish it understoodthat the measuring device may consist of metal, although where the sameis to be used in measuring chemicals or merchandise which will have atendency to corrode metal, the casing and parts associated therewithwhich come in contact with chemicals injurious to metal, may beconstructed of glass or other composition. It will also be observed thatthe interior of the casing is flared toward its outer end, whichconstruction will prevent clogging of the apparatus While in use. I Iclaim: 1. In a measuring device, a casing havlng a passage therethroughand having means.

of connection with a container, a shaft extending through the casingintermediate its length, a trap on said shaft, a weighted crank handleon the shaft, a pivot on the crank handle eccentric to the shaft, a linkhaving a longitudinally disposed slot near one end to receive the pivot,a second trap for guarding said passage, means of connection between'thelink and the last mentioned trap whereby the movement of the linkactuated by the crank handle is communicated to the last mentioned trapfor opening and closing the same in alternation with the closing andopening respectively of the trap intermediate the length of the casing.

2. In a measuring device, a casing having means of connection with acontainer, atrap intermediate the length of the casing, means forsupporting and partially rotating the said trap including a handleoutside of the casing, said handle being provided with means fornormally holding the handle in one position, a trap near the end of thecasing, means for mounting the last mentioned trap on the casing, a linkconnected to and operating the last mentioned trap, said link having aslot longitudinally disposed near its endremote from the last mentionedtrap, a pivot carried by the handle and movable in the slot to permitmovement of the last mentioned trap a predetermined degree independentlyof the movement communicated to the second mentioned trap through theoperation of the link.

In testimony whereof, I afiix my signature in the presence of twowitnesses.
